== Planetary History ==
=== Post-Jihad Years ===
The war between the Taurian Concordat and [[Federated Suns]] officially ended on the 2nd of July [[3080]] in the aftermath of [[Operation MATADOR]], but the fortunes of the Concordat continued to decline. Many worlds, lacking confidence in the Concordat's central government, seceded from the Concordat; Tyrrhenia was the first of the Concordat worlds to do so,<ref name="FM:3085p131"/> leaving the Concordat even before the [[Jihad]] had begun,<ref name="H:MPSp127"/><ref name="J:FRp43"/> and a number of other worlds close to the border of the Calderon Protectorate had done the same by [[3085]]. Where the Taurian government had fought a war a decade before with the breakaway Protectorate, Tyrrhenia and the other worlds that left the Concordat in the aftermath of the Jihad were effectively ignored in favour of reinforcing the narrow salient securing the [[Pleiades Cluster]].<ref name="FM:3085p131">''Field Manual: 3085'', p. 131, "Taurian Concordat"</ref>

=== The Dark Age ===
After the turn of the thirty-second century diplomatic efforts by the rulers of the Calderon Protectorate resulted in the construction of a new military production facility on [[Erod's Escape]], with that construction being supervised by technical advisors from the [[Republic of the Sphere]]<ref name="FM:3145p185">''Field Manual: 3145'', p. 185, "Calderon Protectorate"</ref> and the [[Federated Suns]]. The Protectorate Military Industries (PMI) plant would go on to produce the lion's share of the [[Combat Vehicle]]s that would serve the Protectorate's military forces, while also producing a large proportion of the Protectorate's [[BattleMech]]s.<ref name="FM:3145p188"/> A second, smaller PMI plant was constructed in a similarly supervised fashion on Tyrrhenia.<ref name="FM:3145p185"/><ref name="CGLF20130118">[http://bg.battletech.com/forums/index.php/topic,37430.msg877380.html#msg877380 Aaron "Gravedigger" Pollyea, BattleTech Writer, 10 Mar 2014]</ref>

== Notes ==
It was confirmed by one of the writers that the plant opened on Tyrrhenia in the thirty-second century was a PMI facility, and was still in operation in 3145:<ref name="CGLF20130118"/>

{{Quote|Yes, it was intended to be another PMI facility. It also should still be functioning.<br>
